T 0 all whom it may 'onoern:

Be it known that i, CHRISTIAN Fnnonr, a citizen or? the United States, and. a resielentof the city of New York, borough of Brooklyn, in the; county of Kings and State of New Yorln have invented a new and i provecl Safety Attachmentfor Mold-Liners for Type-Slng-Castinr Machines, of which the following is a fol, clear, and. exact (le scription.

Among the principe object which the )resent invention has in view are: to avoid l damage to iiners used for varying the length of the slug casting mold nseo. in machines of the chareeter mentioned; to avoid deiay in the operation of the machine incident to the stoppage and repair caused by damage done to a liner; and to perfect the mechanism for arresting the opera ion of the cast ing machines when the ej ctors do not correspond with the slug cast.

If at this time the blecie 21 is in its normal depressed. posiiion, the head or the plunger passes over the same without rooi'lng the lever 20 and Witnoet reieasing clutch of the missing machine.

Normally the slide 29 and the face plate thereof is pressed against the head 32 and the wearing point 34 thereof by '1 compression wring 35 (see Fig. 2 of tlu drawings). the arm 2:31 is adjusted in service in corresponden e with the mowimi-nt of the blade lever 34.3. The blade lever 36 is a part of the nit 'hanism hcreiua'ttm' employed for deter-minim); the number of ejector blades em plo vc=.l .oi electing the slug from the mold. To this end the upper end of the blade lever 36 is provid d with numbers intended to de note the length of SlUgKlGSiQIN-Kl to be cast and the width of the ejector blades 37 employed for electing the slug. 'llhelcnglih of the sling is determined by the liner employed. to corrcspoiul with the length of the slug or line of type represent.- ed thereby and as indicated by the nun'icral exposed through the pcep-hole in the frame of the linotype machine. As seen in the drawings, Fig. 1, this peep-hole. shows the numeral 12, which indicates to the operator that the line to be cast is of a 12-111 length. Dilliculties have arisen from the fact that through carelessness or indifference,the liner which is placed in the mold does not correspend. with the adjustment of the mechanism connected with the blade lever :50. or, in other words, the liner placed in the mold may provide for a lO-m length olslug though the mechanism set for slug. Consemicmiy the liner and mechanism connected the; nism, interfei. s, with the result that. the one or other is destroyed. To illustrate a usual form of ejector mechanism, there is shown in Fig". ll of the drawings, the mechanism illustrated in a former Patent, No. 1,099,448, issued June 9, 1914. 1

It will be understood that any other suitable mechanism to selectively control the ejector blades may be employed.

In the mechanism shown in said Fig. of the drawings, the lever 48 is employed to lift the olade 36. A quadrant 49 and griprclease. latch 50 are employed for holding the lew r 48 in adjusted position. The handle 51 If the lever extends to the from" of the machine adjacent the operato1"s working station and manipulatedliy him to lift and depress the slide 53. A-Q'uide bar :36 cxtcndcdlaterally' from the. side supports in sliding relation thereto a plunger 54.. The plunger 54 is suitably connected with. a re- 57, andjextends into the a 112-11: length of 'ewith, or the ejector mecha blades or mechanism directly controlling the same. It will be understood that when the nu-chanisiii for controllipg the plunger 5t eta-responds with the liner l8, the linotypennu'hinc functi ns properly and only at such times. i

In the present attachment. the lever 36 and the selector arm -38 thereof are connected with the arm 33 by means of a plllnger 39. bell crank lever 40, and links 41 and 42. The. plunger 3!) issuitably guided in its operation in bearings mounted in the frame of the casting" machine. 1

The. movement imparted by the lever 36 to the selector arm 35 is increased or diminishcd. as the case may be, ment of the arm of an the blades 37 and mechanism for lllll'OtllltiHgI or retiring said blades from active positions. The total length of travel of the arm 53 and head 32 thereof, corresponds with the dili'cr-' ence in the length of the minimum or maximum extensions ot'the tail-pieces lit with which each of the liners 18 in the present invention is provided. 'lhe'tail-picces 43 ex tend beyond the molds 16 to a plane parallel with and normally juxtaposed to the plane of the lower edge of the head 32.

If by mistake the lever 36 and mechanism connected therewith is not operated to arrange the blades 37 in correspondence with the liner 18, the head 32 will extend below the upper end of the tail-piece 43 of the liner 18.

When, now, the disk and the mold 1G in which the liner 18 is disposed, makes its first movement forward, the end of thetailpiece 43 engages the head 32and forces the same backward against the plate 31 and slide 2!) thereof. The arm 33 is permitted to so move, being pivotally mounted in bearings l4, as shown best in Figs. 1 and f the drawings.

When the tailncce 43 of any liner 18 thus moves the head'32 and slide 29, the knife edge 28 of. the said slide passes out of en gagemcnt with the knife edge to be held against subsequent retraction by the spring When (the disengagement between the two knife edges occurs as state-l, the spring 25 lifts the arm 2b and throu h the connecion, by means of the link -3 into engagement with the plunger 22. When the. disk 15 subsequently moves back, the spring 25 is permitted to fully lift the blade 21 into thepath of, to be engaged by, the plunger 22.

to provide move ascertained ratio to 27, lifts the blade.
